Oceaneering Millennium Plus ROV

설명

The Millennium Plus is Oceaneering's 220 hp heavy work-class ROV for demanding subsea operations. An enhanced thruster configuration gives it more than 50 percent greater lift capacity than the standard Millennium, so it excels in deep water and high currents, and dual high-performance manipulators take it from delicate repairs to heavy lifting in intervention, exploration and construction. The 4,000 kg vehicle measures 3.3 x 1.7 x 1.9 m and is rated to 3,000 m (4,000 m optional). Two 110 hp hydraulic power units drive four vectored horizontal and four vertical thrusters for about 900 kg of forward and lateral and 950 kg of vertical thrust, with hydraulic tool control up to 40 gal/min; the cage adds 110 hp and up to 1,200 m of tether. It is also offered with ROV Integrated Pumping Solutions - RIPS IT3 isolated tooling at up to 3,000 psi, and RIPS BOP for API S53-compliant high-flow blowout-preventer intervention at up to 5,000 psi - and it is the platform whose infrastructure the electric Momentum ROV reuses. It is a side-entry cage (or top-hat) deployed, dual-manipulator heavy work-class ROV with a fly-by-wire station-keeping system, auto heading, depth and altitude, and cruise control, a survey-grade gyro, high-resolution Digiquartz depth sensor and Doppler velocity log, and Kongsberg 1071/1171 or Tritech SeaKing obstacle-avoidance sonar. Cameras run from SD and HD to optional 3D HD, lit by up to eight 250 W lamps, and data links include RS232/RS485, Ethernet and optical fibre. Launch and recovery options include A-frames with or without a docking head, heavy-weather overboarding systems, cursors and heavy-lift winches.
